The Era of Bukht Naṣṣar*
(Nebuchadnezzar).

This monarch instituted an era from the beginning of his own reign. The year is solar, artificial, of 365 days without a fraction. The month, likewise, is of 30 days and five days are added at the end of the year. Ptolemy in his Almagest computed the planetary motions on this era. Since its commencement 2,341 years have elapsed.
